When Turbulent Flow Happens in Sailing
An airplane stalls and falls out of the sky when the wings stop producing as much lift, similar to when turbulent air flow happens in sailing...
Charter Provisioning
Many charter companies can stock and provision your boat before you arrive. This is a good idea for the basics but there is usually little imagination in the food that is supplied.
Sailboat Diesel Engine
Thanks go to Mr. Rudolf Diesel who years ago in Germany cleverly invented an engine that today bears his name (luckily, they chose to use his last name)—the sailboat diesel engine.
Using a Marine Radio
Knowledge of use of a VHF is not only mandatory for safety but some governments require a VHF knowledge certification before you can charter a boat in their waters.
Returning a sailboat to the Slip
Time flies when you are sailing. But sadly, the moment comes when you must return and put your vessel back in its slip.
Sailboat Generator or Large Battery Bank?
Dedicated electric generators on board sailboats are usually only reserved for large sailboats because of their weight and size. Unless there is a desire for large amounts of electricity...
Sail Twist Basics
How can the wind direction be different between the top of the mast and the bottom?
Anchoring
Anchoring is not simply throwing a “hook” and letting out a line. However, after watching some sailors, this seems to be their theory. Successful anchoring requires a plan considering all the factors.
Ferrying Docking Technique
Ferrying is a docking technique whereby you can maneuver your boat in high wind and current easily.
Sailboat Running Rigging
A sailboat’s running rigging consists of those items controlling the sails and helping the sails to capture the wind’s energy.
Understanding Energy and Power
Energy: The concept of energy is likened to water for the easiest understanding. A bucket of water holds a specific amount of water which is measured in a quantity of gallons or liters. It is finite; when it is all drained out, it is gone. To gain more, it must be replaced from a source.
Topping Up your Energy on a Sailboat
There are several methods to top-off your energy on a sailboat.
The Fuel System – Getting Familiar with a Charter Boat
While it is reasonably rare to have a fuel problem on a charter it can certainly happen and you should be prepared to apply the (sometimes simple) solution below.
Dual Rudder Monohulls
When a monohull sailboat has dual rudders, the boat will act with different characteristics than with a single rudder. Thus, the point of this module is to help you maneuver a dual-rudder monohull sailboat.

Sailing Wind Velocity & Direction
The faster the boat sails into the wind, the more the apparent wind speed increases and the more it feels like it is coming from the front of the boat. They say "The apparent wind is forward of the true wind". This means the apparent wind feels like it comes from a more forward direction than the true wind.
Winged Sail Vector Diagrams
Sail and Winged Sail Wind Force Vector Diagrams. And it's highly relevant right now because of the America's Cup AC45 catamarans using winged sails.

Sailing and Wind Forces
A sailboat moves in upwind and downwind directions. Downwind is intuitive; it just gets blown downwind. But just how does a sailboat move into the wind?
Typical Boat and Battery Wiring Schematic
Here is a typical wiring schematic of how your batteries are connected into your boat and charging system.
Sailboat Maneuvering Topics
With practice, wind direction and current direction are not too much of a problem. But what can get you into trouble is extremely high winds. Be prepared to change...
Electric Windlass
An electric windlass is a powerful electric winch that greatly helps in the lowering and raising the anchor.
